ABSTRACT:
A method operating a braking system to prevent or overcome glazing of the brake linings. The brake system has a friction-affected service brake and a wear-free auxiliary brake. A brake value, for instance vehicle deceleration, can be specified to the brakes by a brake value transducer. On the specification of the brake value transducer signals, a control unit triggers the brakes; it detects and evaluates signals characterizing the braking action. Upon a request for braking, the control unit preferentially triggers the auxiliary brake. If the brake value transducer signal level is high, it additionally switches on the service brake. The control unit detects the number of braking events of the service brake and their intensity (duration, action, etc.). As a function of these data, the control unit detects a threatening danger of glazing or glazing that has already begun and triggers the service brake exclusively. The brake linings of the service brake undergo "deglazing" by braking, by way of an adequate temperature rise.
